Area of Science:

Computer Vision
Robotics
3D Reconstruction

Background:

High-resolution RGB-D sensors are crucial for computer vision, manufacturing, and robotics.
Depth maps from these sensors suffer from inherent measurement uncertainty (noise), degrading 3D reconstruction quality.
This noise limits the suitability of current sensors for high-precision applications.

Purpose of the Study:

To quantify depth map uncertainty in high-resolution RGB-D sensors.
To develop a noise model for improving 3D reconstruction accuracy.
To analyze factors affecting depth map quality.

Main Methods:

Estimated a noise model for a Zivid structured light sensor mounted on a robot arm.
Considered measurement distance, surface angle, background light, exposure time, and number of captures.
Integrated the noise model with classical (KinectFusion) and neural rendering-based (Point-SLAM) algorithms.

Main Results:

Developed a noise model accounting for sensor distance and angle.
Analyzed the impact of environmental and operational factors on depth map quality.
Demonstrated improved tracking and higher-resolution 3D model generation using the noise model.

Conclusions:

The proposed noise model effectively quantifies RGB-D sensor uncertainty.
Integrating this model enhances the accuracy of 3D reconstruction algorithms.
This work advances the application of RGB-D sensors in high-precision fields.
